The NQFL is a grid consisting of eight levels in which all formal qualifications of the Liechtenstein VET system are systematically classified. This is done through action-competence-oriented descriptors, which describe the requirements for each level. The levels of the Qualifications Framework correspond with those of the EQF. The descriptors also closely relate to those of the EQF. In order to adequately clasyify them they were adapted to the special features of the Liechtenstein VET system, particularly the importance of periods of practical training.  The descriptors of the NQFL are formulated in a VET-specific way across all eight levels. The SBFI carried out the elaboration.

The three descriptors «knowledge», «skills» and «competences» are defined for specific use in Liechtenstein VET:

• "Knowledge" refers to declarative knowledge in a field of work or learning and is divided into the categories "knowing" and "understanding".
• "Skills" refers to the ability to apply knowledge in order to carry out tasks and solve problems. A distinction is made here between procedural and sensomotor skills.
• "Competences" express the constant and routine exercise of knowledge and skills in a work enviorment and are divided into "professional" and "social" competences. The wording of this descriptor reflects the importance of practical experience.
• They show that skills are acquired that go beyond the professional field and promote the further development of the individual in- and outside of their work field.

Level 1 is unlikely to be occupied by vocational qualifications. Levels 2 to 5 are available for basic VET, depending on the qualification.
Levels 5 or 6 to 8 of the EQF are open not only to higher education qualifications but also to VET qualifications at tertiary level (higher VET) and will be shown in the Y-frame on the left. However, Liechtenstein does not currently award diplomas at the tertiary level.

A decisive criteria for the classification of occupations in the NQFL is the competence to act. All VET qualifications are assessed on the basis of these competences and assigned to a level in the NQFL.

The action competence orientation also makes it possible to adequately reflect the amount of practical experience, which is important for the VET system, in the Qualification Framework. In the area of basic VET, practical experience is an integral part of an appprenticeship The learning goals are regulated in the respective education ordinances. The providers of practical VET, i.e. the companies themselves, are committed to the best possible learning outcomes for the apprentices and periodically review their progress. As the classification of basic vocational education and training is based on the education regulations, the practical professional experience of the graduates is automatically taken into account for allocation to the NQFL.
